Testing and Analysis of Load Fracture Damage of PVA Fiber Reinforced Concrete Bending Beams
Four point bending experiments were conducted on PVA fiber reinforced concrete beams with different incision depths.Combined with the double K fracture criterion,the initiation strength factor and instability strength factor of beams with different opening depths were calculated.The crack opening displacement and cohesive stress in the fracture process zone of PVA fiber reinforced concrete were calculated using the quasi brittle calculation formula.
